Hi CILI~ Your weight stayed about the same today, and although the fat reading looks lower, your moisture went up quite a bit — this is a water shift (you're on day 2 of your period, so some water retention is completely normal), not a real fat change, so let's read it gently rather than as a sudden drop.
Yesterday's meals were clean (wow, egg white, salad) and I saw you had your Joy123 — great for your gut 👍 The lunch salad sounded too spicy/uncomfortable; today maybe go for something milder.
Keep your water up like today (3300ml is great). You're doing really well~
